l The features of my invention consists in the improvementshereinafterdescribed and illustrated, wherein a column of clay is causedto flow continuously from the forming die of the forcing machine, havingseveral ribs raised up on one surface of saidmoving column.

transverse grooves in said die formed ribs, so that when said bricks arelaid in a pavement, and a fluid filler is poured into the crevicebetween said brick, said'fluid filler ressed into said die formed ribsand como pletely fill all the voids between thepaving bricks.

These and other features of my'invention will appear hereinafter, andare --illustrated in the accompanying drawings as follows, viz

l on the line 2-2 in Fig. 1.

Figure l is a side view in elevation of a portion of a brick makingmachine embody ing my invention. g 3 i Figure 2 1s a transverse sectionof the same Figure 8 is a view similar to Fig. 1 of the same on anenlarged-scale, with a portion broken away. 1

' The wire cutting machine by which the column of clay is dividedintobricks is not shown, as the same is old and well known and forms no partof the present invention.

In these drawings A indicates the forming die of a forcing machine whichforms'the clay 7, Also in providing a roller providedwith transverseribs which are adapted to form .wirecutting'machine, not showing.Secured to the frame B, B, are uprights C O, in.

"The sidebars-D are provided with acrossbar F, see Fig. 2,'andw1tha crossbar F by means Theroller E isprovided withribs E which are of suflicient size that when pressed into.the ribs G of the clay column will form transverse grooves 9, see Figs.5 and? there in, so that when the bricks have been dried and baked, theywill have lugs H thereon, see Figs. 7 and 8.

of which said side bars Dj-are maintained in l The transverse cutsurface shown in Fig. 6

rod D can be raised upward the frame D and e 7 roller E can beremovedfrom engagement with the uprights C" and removed bodily. whendesired.

In Fig. 3, the openings 0 in the uprights I C are elongated, and areprovided with an rod therethrough, so that the frame and roller-E can beremoved, or replaced without removing said uprights C. The axle e issecured to the sidebars D by means of U-shaped bolts 6 or in any othersuitable manner, so that saidaxle will notmove laterally with.

reference to said side bars D.

will be laid up, with the lugs H on the die 7 opening 0 to admit of thepassage of the pivot Having thus fully described the mechanism by meansof which spacing lugs can be formed on the die formed surface of bricks,I do not desire to be limited to the exact construction shown anddescribed as many modifications can be made therein Without departingfrom the scope of my invention, therefore What I claim as new and desireto secure by Letters Patent is:

A machine for making paving brick, comprising a forming die havingspaced slotted portions in its upper Wall adapted to provide a claycolumn with spaced longitudinal ribs on its upper face, a traveling beltfor receiving the clay columns, spaced standards at opposite sides ofthebelt having 'rearwardly opening shouldered sockets therein, a freelyfioatingframe fitting at its forward end between the standards, a rollermounted in the frame and having spaced transverse peripheral ribsadapted for embedding in said ribs of the clay column to form spacedpairs of spaced projections on the clay column, and a rod extendingthrough the forward end of 1 the frame and extending therebeyond forengagement in said sockets of the standards for detachably and pivotallyconnecting the frame to the standards.

In testimony whereof I affix my signature.

JACOB NESSLY PORTER.
